Great, but couldn't you type some command which would screw it up, by accident?

What do you mean?

Say your implementation uses some global variable called $history.

Not global variables but class attributes.

Now say I type "$history = [];" at the interactive prompt. Won't that break it?

Of course not. We read chars one by one on stdin. If a mapping is detected, then we call the associated callable. The line is never executing/evaluating as a PHP code (except if this is what you want obviously). Eh? I thought PHP interactive evaluated the code? What's the use of only being able to use functions?
